Sleep disorders, such as restless legs, periodic limb movements and sleep apnea, and sleep complaints such as insomnia and daytime sleepiness, are very common in end-stage renal disease patients despite treatment with 3-times-a-week conventional hemodialysis. If left untreated, they are likely to impair quality of life and may alter cardiovascular outcomes in this patient population. Home dialysis has the potential to improve sleep disorders by offering more effective dialysis than conventional modalities. Although there has been little direct comparison between the impact of home dialysis and conventional dialysis on sleep disorders, there is evidence that both nocturnal peritoneal dialysis and nocturnal hemodialysis improve sleep apnea. The impact of home dialysis on other sleep disorders and sleep complaints is less impressive, but the data, thus far, have been limited. Further research is required to evaluate the impact of home dialysis on all sleep disorders and sleep complaints in this patient population and to determine whether this improves quality of life and cardiovascular morbidity and mortality.

Sleep-related disorders are most prevalent in the older adult population. A high prevalence of medical and psychosocial comorbidities and the frequent use of multiple medications, rather than aging per se, are major reasons for this. A major concern, often underappreciated and underaddressed by clinicians, is the strong bidirectional relationship between sleep disorders and serious medical problems in older adults. Hypertension, depression, cardiovascular disease, and cerebrovascular disease are examples of diseases that are more likely to develop in individuals with sleep disorders. Conversely, individuals with any of these diseases are at a higher risk of developing sleep disorders. The goals of this article are to help guide clinicians in their general understanding of sleep problems in older persons, examine specific sleep disorders that occur in older persons, and suggest evidence- and expert-based recommendations for the assessment and treatment of sleep disorders in older persons. No such recommendations are available to help clinicians in their daily patient care practices. The four sections in the beginning of the article are titled, Background and Significance, General Review of Sleep, Recommendations Development, and General Approach to Detecting Sleep Disorders in an Ambulatory Setting. These are followed by overviews of specific sleep disorders: Insomnia, Sleep Apnea, Restless Legs Syndrome, Circadian Rhythm Sleep Disorders, Parasomnias, Hypersomnias, and Sleep Disorders in Long-Term Care Settings. Evidence- and expert- based recommendations, developed by a group of sleep and clinical experts, are presented after each sleep disorder.

Sleep disturbances in chronic peritoneal dialysis (PD) patients are increasingly widely recognized. These include changes in sleep architecture, sleep apnea syndrome, restless legs syndrome, periodic limb movement disorder and excessive daytime sleepiness. Some of these entities will be addressed in this review. The study tools for detecting sleep-related disorders in PD patients range from self-reported questionnaires (subjective) to standard overnight polysomnographic measurements (objective). Both these tools identify a high prevalence (over 50%) of sleep-related disorders among dialysis patients. Among these, sleep apnea syndrome is one of the most widely reported sleep-related disorders in PD. Sleep apnea in PD may be attributed to chronic fluid overload and uremia, leading to both obstructive and central forms of apneas. The exact underlying pathophysiology, however, is complex and likely involves a combination of multiple factors. There are preliminary data that nocturnal PD may be advantageous over conventional continuous ambulatory peritoneal dialysis in correcting sleep apnea associated with PD. Randomized studies are needed for confirmation.

Hypertension can cause or promote renal failure and is related to cardiovascular mortality, the major cause of death in patients with renal impairment. Changes in the circadian BP pattern, particularly the blunting or reversal of the nocturnal decline in BP, are common in chronic renal failure. These changes in turn are among the major determinants of left ventricular hypertrophy. Using a chronobiological approach, it is possible to obtain better insight into the reciprocal relationship between hypertension, renal disease, and increased cardiovascular risk of renal patients. Disruption of the normal circadian rhythm of rest/activity may be hypothesized to underlie the high cardiovascular morbidity and mortality of such patients. Epidemiological studies reveal that hemodialysis patients experience poor subjective sleep quality and insomnia and, in comparison to healthy persons, are more likely to show shorter sleep duration and lower sleep efficiency. Sleep apnea may be present and is usually investigated in these patients; however, the prevalence of restless legs syndrome (RLS), which is high in dialysis patients and which has been associated with increased risk for cardiovascular disease in the general population, could also play a role in the pathogenesis of sleep-time hypertension in renal patients. Careful assessment of sleep quality, in particular, diagnostic screening for RLS and periodic limb movements (PLM) in renal patients, is highly recommended. In renal failure, attention to sleep quality and related perturbations of the sleep/wake cycle may help prevent the occurrence and progression of cardiovascular disease.

The feature of a dialysis patient's sleep disorder is that deviation with a feeling of subjective sleep and an objective sleep disturbance is large, and subjective symptoms are scarce considering serious sleep disorders. The feature of a dialysis patient' s sleep disturbance is characterized by increase in time to awake on bed and the fragmentation of sleep, which lead to reduction in sleeping hours. The prevalence of SAS (sleep apnea syndrome) in the dialysis patient is several times higher compared with the commoner. The prevalence of RLS (restless legs syndrome) in Japanese dialysis patient was almost even with Westerners patient. Otherwise it tends to underestimate sleep disturbance, our questionary survey revealed high prevalence of subjective sleep complaints in dialysis patients. The realities of dialyzed patient' s sleep disturbance might be more serious than we think.

Alterations of sleep structure with aging are attributed to change of circadian sleep-wake system and decrease of daytime activity with aging. Prevalence of insomnia and use of sleeping pills increases with age. Physical and psychiatric conditions play important roles in poor sleep in old age, and restless legs syndrome and sleep disordered breathing increase with aging as well. Early and appropriate intervention to insomnia will contribute to improvement of health and quality of life in the elderly.

Patients with multiple sclerosis (MS) often have unrecognized sleep disorders at higher frequency than the general population. Sleep disorders such as sleep disordered breathing, insomnia, REM sleep behavior disorder, narcolepsy and restless legs syndrome have all been reported in the MS population. Notably, the most common symptom of MS is "fatigue," which itself has been correlated with sleep disturbances. Sleep disorders may impact the quality of life of the MS patient population. This paper reviews the association of sleep disorders with MS, and discusses the association of sleep disruption with MS fatigue.

Over the past decade substantial evidence has accumulated implicating disorders of sleep in the pathogenesis of various metabolic abnormalities. This review, which is based on workshop discussions that took place at the 6th annual meeting of the International Sleep Disorders Forum: The Art of Good Sleep 2008 and a systematic literature search, provides a critical analysis of the available evidence implicating sleep disorders such as obstructive sleep apnoea (OSA), insomnia, short or long-term sleep duration and restless legs syndrome as potential risk factors for insulin resistance, glucose intolerance, type 2 diabetes mellitus and the metabolic syndrome. The review also highlights the evidence on whether treatment of specific sleep disorders can decrease metabolic risk. In total, 83 published reports were selected for inclusion. Although several studies show clear associations between sleep disorders and altered glucose metabolism, causal effects and the underlying pathophysiological mechanisms involved have not been fully elucidated. OSA appears to have the strongest association with insulin resistance, glucose intolerance, type 2 diabetes and the metabolic syndrome. There are, however, limited data supporting the hypothesis that effective treatment of sleep disorders, including OSA, has a favourable effect on glucose metabolism. Large randomized trials are thus required to address whether improvement of sleep quality and quantity can curtail excess metabolic risk. Research is also required to elucidate the mechanisms involved and to determine whether the effects of treatment for sleep disorders on glucose metabolism are dependent on the specific patient factors, the type of disorder and the duration of metabolic dysfunction. In conclusion, there is limited evidence on whether sleep disorders alter glucose metabolism and whether treatment can reduce the excess metabolic risk.

Sleep-disordered breathing (SDB) encompasses a group of disorders that include obstructive sleep apnoea (OSA), central sleep apnoea (CSA) and nocturnal hypoventilation. SDB commonly coexists with sleep disorders such as insomnia and restless legs syndrome, and sleep deprivation has been shown to play a role in the pathogenesis of SDB. Participants of a workshop, held at the 6th annual meeting of The International Sleep Disorders Forum: The Art of Good Sleep in 2008, evaluated whether the effective management of sleep disorders could result in a reduction in SDB. Following the workshop, a critical review of the literature in the field of sleep and SDB was conducted in order to assess the impact of improving sleep on SDB, and to determine whether measures taken to improve sleep result in a subsequent improvement in SDB. Results showed that studies evaluating the influence of improved sleep on respiratory abnormalities in patients with SDB are lacking. Studies in patients with OSA, with or without obesity-hypoventilation syndrome, show that therapy with continuous positive airways pressure and non-invasive ventilation improves sleep parameters with beneficial effects on SDB. Studies involving small numbers of patients have shown that the antidepressants fluoxetine and mirtazapine produce improvements in sleep parameters and the apnoea-hypopnoea index, and that acetazolamide may improve CSA. The benzodiazepines flurazepam, temazepam and nitrazepam, the hypnotic zolpidem, the melatonin receptor agonist ramelteon and gamma-hydroxybutyrate have all been shown to improve sleep, but are not associated with reductions or worsening in SDB. It is clear that there is a distinct knowledge gap with regard to the benefit of improving sleep disturbances for subsequent improvements in SDB. Randomized controlled clinical trials investigating the effect of pharmacological and non-pharmacological improvement of sleep disorders focusing on whether there is improvement in coexisting OSA/SDB are clearly needed. Furthermore, well-designed clinical trials investigating the role of hypnotic agents in improving SDB in certain phenotypes will enable the development of treatment recommendations for primary care physicians managing these patients in routine clinical practice.
